Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a glass plate mounting structure.

[Prior Art] A so-called structured silicone method of fixing a glass plate by adhering one surface of the glass plate to a sash with a silicone resin adhesive is widely known.

4 and 5 are cross-sectional views showing a conventional example of the structural silicone method.

As shown in the figure, the glass plate 1 is adhered to the frame body 2 with the silicone adhesive 3, and the glass plate is fixed to the frame body only by the adhesive force of the adhesive. In the figure, 4 is a sealant, and 5 is a glazing bead for keeping the distance between the glass plate and the frame at a predetermined value. This structure silicone method has an advantage that a flat glass-walled wall surface in which the sash frame does not project outside from the glass plate surface at all can be obtained, but has the following problems.

The structure silicone method does not put the glass in the metal frame, but adheres it to the metal frame with silicone and holds it.
All of its safety depends on the reliability of the adhesive strength of silicone. With regard to the durability of silicone itself and the durability of the adhesive force between silicone and glass against aging, there is already 20 years of experience since 1965, and it is no accident. However, regarding the adhesive force between silicone and metal, the reliability cannot be said to be perfect even after the cleaning primer treatment, and the cause of water leakage is caused by the interfacial peeling between silicone and metal. Therefore, if the glass is adhered to the metal frame only with silicone within the space as shown in FIG. 4 or 5, if the interface peels between the silicone and the metal frame, the glass will drop as it is. The possibility arises.

[Problems to be Solved by the Invention] The present invention aims to solve the above-mentioned problems that the prior art has.

[Means for Solving Problems] The present invention has been made to solve the above problems, and in a method of fixing a glass plate by adhering the glass plate to the frame with an adhesive, the glass plate of the frame is used. The mounting surface is provided with a groove of a diverging shape having an inner part of a cross section parallel to the surface to which the glass plate is to be adhered, which becomes larger toward the back, and an adhesive for fixing the glass plate is filled at least along the groove surface. It is characterized by being allowed to solidify.

In the present invention, any adhesive can be used as long as it has weather resistance and adhesive strength, but a gel-type silicone adhesive is particularly preferable. In the present invention, a groove having a flared shape is provided in the frame body to which the glass plate is to be fixed. The splayed shape is a shape in which the inside of the groove has a portion where the parallel cross-section increases toward the back in the surface to which the glass plate is to be bonded so that the solidified adhesive functions as an anchor, and the groove width is not necessarily the back. It is not necessary to form the groove so that it becomes larger as a whole, and it is also possible to use, for example, one in which the wall surface of the groove is formed in a zigzag or arrowhead-shaped unevenness. The groove is usually provided continuously on the glass plate mounting surface of the frame body, but it may be provided as a hole at a predetermined interval. In addition, the glass plate mounting surface of the frame body to which the adhesive is applied has been cleaned with a primer treatment in advance,
Further, it is suitable to provide a glazing bead for keeping the distance between the glass plate and the frame at a predetermined value.

To attach the glass plate, you may press the glass plate after applying an adhesive to the glass plate attachment surface of the frame and the groove, but normally, use a sizing bead or the like to hold the glass plate in place in advance. In advance, the adhesive is injected into the space between the glass plate and the frame and into the groove using a caulking gun or the like.

The glass plate is fixed to the frame by the solidification of the adhesive, and even if peeling occurs on the adhesive surface with the frame, the groove has a flared shape, so the adhesive solidified in the groove acts as an anchor. However, the glass plate does not fall.

Next, an embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a sectional view showing a first embodiment of the present invention, in which a groove 6 having a truncated trapezoidal shape is formed in the metal frame body 2, and the silicone adhesive 3 is attached to the glass plate mounting surface of the metal frame body 2. Then, the glass plate 1 is applied in the groove, and the glass plate 1 is pressed and adhered to the metal frame. In this case, the metal frame body 1 is attached to a construction body such as a building, although not shown. In the figure, 5 is a glazing bead, 4 is a silicone-based sealant, and one end thereof is filled in a groove of a flared shape provided in the sash.

FIG. 2 shows another embodiment of the present invention, in which a sealant 4 is provided on the end face of a glass plate 1 adhered and fixed to a metal frame 2 with a silicone adhesive 3 to seal the joints of the glass plate 1.

FIG. 3 shows an example in which grooves 6 having zigzag-shaped irregularities are provided on the inner wall of the metal frame body 2 on the glass plate mounting surface.

[Advantages of the Invention] The adhesive solidified in the groove plays the role of an anchor, and even if peeling occurs on the glass plate mounting surface of the frame, the glass plate does not fall off, and the reliability of the structural silicone method Can be even greater.
